Data from SEAPOP’s network of seabird colonies along the Norwegain coast and on Svalbard show that breeding phenology varies a lot between species, and depends on different factors.
In a recently published study, researchers investigated variations in the timing of breeding among kittiwakes, puffins and common and Brünnich’s guillemots in Norway and Svalbard. The colonies cover an extensive latitude gradient (65-79º N), and the results suggest that several mechanisms affect the timing of breeding for the different species.
